Removed Fortran from NetCDF build

Fortran support has been explicitly disabled in the NetCDF brew pending
the resolution of Issue 72. It is perfectly possible to use the brew to
build a working Fortran NetCDF library if a Fortran compiler is present.
However, configure may fail on 64 bit architectures as Homebrew does not
set the FCFLAGS and FFLAGS environment variables to be compatiable with
those set for CFLAGS.

The best resolution of this issue is formal support for a Fortran
compiler.

A non-existant configure argument related to Szip was removed. This
dependency is satisfied by specifying the location of HDF5.

+This brew of NetCDF does not include Fortran support.
+Fortran support will be added once the following issue

+
+If you have a Fortran compiler and would like to enable
+NetCDF support for Fortran compilers, execute:
+
+  brew edit netcdf
+
+Comment out the configure argument disabling Fortran
+and re-install.  You may have to set FCFLAGS and FFLAGS
+to be consistant with Homebrew's use of C compilers in
+order for the brew to install correctly.
+
+Be aware that the Homebrew project may not be able to
+provide support for any issues that arise during
+compilation when Fortran is enabled until a Fortran
+compiler is officially supported.
